A “High Density Cluster” - HDC (also “Urban Centre”) consists of contiguous grid cells (4-connectivity cluster) with a density of at least 1,500 inhabitants per km2 of permanent land, and has at least 50,000 inhabitants in the cluster with smoothed boundaries (3-by-3 conditional majority filtering3) and <15 km2 holes filled. |
